By the employment of the presser bar such as I have devisedthe pressure to collapse or deflate the bag is distributed substantiallythroughout the length of the bag; making for a more complete collapse orcompression of the bag and facilitating the intake of a greater quantityof ink to fill the bag upon release of the lever than is possible withpresser bars having a single portion acting from a single fulcrum pointadjacent one end of the shell or barrel under the influence of the usuallever carried thereby.

By preference the active portion of the presser bar is made of acorrugated section of suitable spring metal, as clearly shown in Figs. 4and 5; each portion; 11, l1a and 12, being corrugated. And suchcorrugations may extend throughout the full extent of the presser bar orthe active portions alone may be corrugated. Such corrugations add acertain amount ofstiffness and strength to the portions 1l, 11a and 12of the presser bar without affecting the desired resiliency orflexiblity or the ability of such portions to bend and automaticallydevelop fulcrurn points Without destroying the'elastic limit of themetal comprising such presser bar.
